Trial Purpose:
Evaluate effectiveness for three products at increased time and concentrations
Date Run:
04/01/2002Experiment Procedure:
The three products that showed improvement in the previous trial were diluted to 10% using DI water in 600 ml beakers. Each solution was heated to 110 F and degassed for 5 minutes in a Crest 40 kHz Ultrasonic unit. Nine preweighed coupons were coated with the beeswax and weighed again. Three coupons were cleaned for 10 minutes followed by a tap water rinse at 120 F for 15 seconds and a heat gun drying at 300 F for 1 minute. Final weights were recorded and efficiencies were calculated.
Trial Results:
Increasing the cleaning time and concentrations increased the efficiency for the three products tested. Inproclean and Texolite removed over 95% of the wax in the 10 minutes. The Polyspray product increased from 73% to 80%.
| Cleaner | Coupon 1 | Coupon 2 | Coupon 3 | Average | Std Dev |
| Inproclean | 97.74 | 101.01 | 98.73 | 99.16 | 1.68 |
| Texolite | 98.23 | 98.47 | 94.07 | 96.92 | 2.47 |
| Polyspray | 83.29 | 74.56 | 83.16 | 80.33 | 5.00 |
Success Rating:
A follow up test, usually based on company input.Conclusion:
The effective cleaners will be tested on wax removal from glass coupons using ultrasonic energy. Cleaners to evaluated are: Inproclean 3800, Texolite 1734 XL, Bio T 200 A, Histo Clear and Opti Clear.
